If you want to call them a series, it would be 45-49. (Big frame starts at 4640, 4650, 4555, and 4560.) Also, the 7.6 liter motor in the 55 and 60 tractors (maybe 50 as well) is not the same as the 466 in the 4240 to 4640 tractors, despite having the same displacement. Good tractors, and the 7.6 motor was also used in the early 8000 tractors. Agree the cabs are definitely better in the 8000 tractors.
